At the office you might have a security team who works hard to ensure your data is protected. But what about protecting your security at home? As of late, it seems like nearly everything is connected to our Wi-Fi. From multiple laptops and cell phones, to thermostats and light switches, smart technology makes our lives easier. And now in the age of social distancing, we are relying on our home networks more than ever. But the idea of being responsible for keeping your personal network connections and devices secure can be daunting. Does this mean you should live in a constant state of fear that someone will hack into your network or devices? No. But you do need to know about some steps to take to protect yourself. So \u2026 what threats should you be worried about, exactly? Most common threats For the purpose of this post, let\u2019s put vulnerabilities into three buckets \u2013 networks, endpoints and online behavior \u2013 and talk about why you should care. Networks If it\u2019s connected to the internet (laptops, TVs, voice assistants, etc.), then it can probably access other devices at home. Which means there are ample opportunities for attackers to find entry as we transmit data throughout our networks. But, unless you live off the grid, you don\u2019t have much choice except to rely on the internet to function in society. Think about securing your networks like locking your doors at home. You don\u2019t want attackers to come in and steal your belongings. And you definitely don\u2019t want them using your home to conduct criminal activity (resulting in the FBI busting down your door). Opening a port on your router for a game, connecting a thermostat to the cloud, even giving a visitor your Wi-Fi password for their phone \u2013 these can all open our networks to potential threats. Luckily, there are relatively simple ways you can make sure no one is slipping in your back door while you aren\u2019t paying attention (check out the 10 tips at the end of this post). I also get a lot of questions about using public Wi-Fi. Here\u2019s my advice: getting attacked while using public Wi-Fi isn\u2019t probable if you aren\u2019t a big target, but it is possible. That\u2019s why it\u2019s important to be thoughtful when you are using networks outside of your home. Improve your security on public Wi-Fi by using a VPN, or avoid the Wi-Fi altogether and tether to your cell phone (ideally with a cable). Endpoints Many built-in services on laptops can create more opportunities for attackers. A well-known attack is a fake \u201chelp desk\u201d call, tricking someone into granting remote access to their screen. Unless you directly call for IT support, no one needs you to share your screen or to enable remote control. Avoid keeping file sharing features like AirDrop on (and even then, set to accept files from contacts only). Turn on file sharing and remote access only when you need it, and turn it off again once you\u2019re done. Think about the apps you use, too. Be careful when installing an app that asks you to change network settings \u2013 it could be trying to watch your web traffic. And if an application asks for access to your location, contacts, or other privacy-related content, don\u2019t say \u201cYes\u201d unless you understand exactly why it\u2019s asking. As a general rule, lock your computer screen if you get up to grab a cup of coffee and put a lock on your cell phone screen. It\u2019s helpful to update your settings so your screen locks automatically after being idle for five minutes. Sure, locking screens might matter a little less if you live alone and are working from home, but these are still good habits to adopt. Online behavior Attackers often count on us to make a mistake and accidentally open the door for them. Think about the number of times you enter your bank and credit card information when you\u2019re ordering groceries from Amazon. Make sure you\u2019re shopping through reputable dealers and avoid storing your credit card information on a website. Many banks will allow you to set up text message alerts for large purchases or unusual activity \u2013 a smart feature to enable, to be on the safe side. Then there\u2019s phishing. What makes something look suspicious? Emails with a sense of urgency or a time limit, obscure invoices and warnings of disastrous outcomes are all red flags. Pop-ups that won\u2019t go away or are asking you to download something are often nefarious. Make sure you also hover over links and investigate them before clicking them. Do I need to bother mentioning that you shouldn\u2019t plug an unknown USB drive into your computer? Just in case\u2026don\u2019t do that. Don\u2019t be too quick when granting access to shared documents in G-suite or iCloud, for example. Make sure people and organizations can be vouched for and are trusted before granting access. Watch what you share on social media. Never give out your address or personal information. Hackers can search on social media sites to find answers to security questions. Tips and tricks for computer safety and privacy We\u2019ve only scratched the surface and already this looks like a lot of work. How can you make sure you aren\u2019t allowing yourself to be a target without spending your entire day thinking of all the ways you can be attacked? Use these 10 tips and tricks. Create strong passwords, don\u2019t reuse them on different sites, and ALWAYS use MFA \u2013 multi-factor authentication \u2013 when given the option (these are one-time passwords, push messages, even text messages in a pinch). Also, use a password manager application! A good password manager can make it easy to select strong, unique passwords, and should support many built-in MFA systems. They can warn you if you\u2019ve accidentally reused a password, or if you forgot to enable MFA. They can even alert you when sites you visit have had a recent password breach. Keep your software updated on operating systems, apps, laptops, cell phones and routers. Vendors are constantly patching bugs and security holes, some of which can be critical entry points for an attacker. Most operating systems and app stores can automatically update their software for you. Keeping your home network updated (Wi-Fi routers, etc.) isn\u2019t quite as critical, but if it\u2019s been years since you looked at your router, it may be a good idea to check for updates. Use WPA2 with a strong password when setting up Wi-Fi at home. For your visitors, consider setting up a guest network with a different network name and password. Disallow remote access to your network and desktop (remote login, screen and file sharing, etc.) by disabling it on your computers and limiting the number of ports you let through the internet router. When you do need it, enable it only for the time you\u2019ll be using it, and then immediately turn it back off again. Create a separate administrator account, and use a non-admin account for day-to-day activity. By keeping your administrator \u201cpersona\u201d separate from your daily use account, you lessen the chance that you may accidentally install malicious software without paying attention (many of us are a little too quick to click that \u201cOK\u201d button when we are prompted). By forcing you to switch to a different account, you ensure that a random, \u201cOh, I need your admin password now,\u201d prompt isn\u2019t going to break your computer, and makes installation of software and system-level changes a much more explicit action. Be careful with what you share online. Many sites still use \u201csecret questions\u201d to help you recover passwords. But a secret question like \u201cWhat brand was your first car?\u201d is only secret if that information is hard to find. Many common secret questions end up being things that people frequently share online (as part of a Facebook profile, or some forgotten tweet that might be easily searched for). Still others may be found from common data aggregation services \u2013 it\u2019s surprisingly easy to find the last five home addresses for just about anyone, often for no charge. Also, you should be careful not to give away too much about where you are (\u201cI\u2019m in Europe for a month, and our dogs are at the kennel, so our big suburban home in the wooded neighborhood is COMPLETELY UNATTENDED.\u201d) It\u2019s not likely that burglars are trolling social media to find targets, but you shouldn\u2019t make it too easy for them, either. Be thoughtful about the apps you install and always download from a trusted app store when possible. The \u201cbig\u201d app stores (Apple, Google, etc.) do a pretty good job of making sure that malicious software is kept out, and sticking to just those sources will go a long way to keeping you safe and secure. Whenever something (especially a website) prompts you to download a \u201cspecial app,\u201d don\u2019t download it right then and there. Instead, note what the file is (or does) and try to find it, or a suitable equivalent, in one of the main app stores. Even if you can\u2019t find it in the app store, if you can independently source it on the web, rather than taking the version the website just offered, that\u2019s usually a better plan. Have a keen eye for phishing and social engineering. Scams still come through email more than any other method, but the phone is a growing source of computer attacks. The most common is some variant of a \u201chelp desk\u201d calling to warn you that your computer is compromised, and asking you to do things to help them secure it (which instead just opens it up to their attacks). Plus there are all manner of old-school confidence tricks that people still succeed in pulling off, through phone calls, text messages and email. Learn how to recognize these, and swiftly ignore them when they happen (hang up, delete, etc.). If your router (and tech-fu) supports it, put all your internet of things, er, things (security cameras, baby monitors, refrigerators, smart-locks, etc.) on a totally separate network with its own access point. This is a great place to put your guest network as well, though they\u2019ll lose the ability to interact with your TV, etc. Backups, backups, BACKUPs! Backing up your data is a pain. Do it anyways. Follow the 3-2-1 rule: Keep 3 copies of your data; on 2 different systems (for example, one in the den, one in the basement); and 1 off-site (like at a friend or relative\u2019s house). Keeping two copies at home protects you against a single computer failure or breach, keeping one outside of the house protects you against a house fire. Cloud based services like Backblaze are fantastic for offsite backups. Have a question about keeping your stuff secure at home?
